Final answer:
Released men from Andersonville faced harsh post-prison conditions, but were not executed or sent to Great Britain. Instead, their experiences after release reflected the dire circumstances of the time, and as the Civil War ended, national focus was on reconstruction and healing.
Step-by-step explanation:
The fate of the men released from Andersonville, the Confederate prison camp, varied. Instead of direct execution, many faced dire situations due to severe resource shortages. The practice of exchanging prisoners early in the Civil War ceased as the war progressed, leaving the Confederacy and the Union with the challenge of housing and providing for a growing number of prisoners.
Conditions in camps were notoriously poor, with high mortality rates. Upon release, some prisoners were exchanged or paroled if they survived to see the war's end, but they were not sent to Great Britain nor offered to fight for the CSA as a general rule. Post-war, the focus shifted to healing the nation and integrating freed slaves into society.
